NON-REFILLABLE BOTTLE.

SPECIFICATION forming part of Letters Patent No. 631,258, dated August 15, 1899.

. Application filed January 20,1897. Serial No. 619,866. (No model.)

T a/ZZ whom, it may concern:

Beit known that I, GEORGE MCEACHRON, a citizen of the United States, residing at Brampton, in the county of Delta and State of Michigan, have invented certain new and l useful Improvements in Non-Refillable Bottles; and I do hereby declare the following to be a full, clear, and exact description of the invention such as will enable others skilled in the same. y

This invention relates to improvements in non-refillable bottles; and it consists in certain combinations, details, and arrangement of parts, all of which will be hereinafter first the art to which it appertains to make and use described and then specifically pointed out.

in the appended claims, reference being had to the accompanyingdrawings, in which- Figure l is an exterior view of the bottle zo constructedinaccordance with myinvention.

in which like letters indicate like parts in all the figures, ct represents the bottle proper,`

and b the main stopper portion thereof.

4o The bottle may be of any desired construction and material, with the exception that its neck portion has an internal annular groove A, for the purposes hereinafter described.

The stopper proper,,comprises two sections b b', respectively, the section b being pro-` vided at its upper end with an escape-aperture b2, which during shipment or standing said section b and under the said block.

-at their'upper ends to the material forming the head of the section b and projected down and outward, so that when the stopper is forced into the neck of the bottle the projecting portions b5 will snap into the annular groove A, and thus hold the stopper b securely in position in the neck of the bottle against Withdrawal.

While fitting the stopper into the neck the spring b4 will compress into the slots b3 within vthe interior of the section b, they only springing out of a locked position when the eXtensions b5 come in line withthe annulargrooves 65 a a. v v

The section b is provided-with avalve-guard C, which consists of a block of glass, porcelain, or other suitable material, its sides having formed therein an annular groove C', 7c while its top is provided with agroove c', extending diametrically across the same and at a suficient depth to unite with the annular 'groovec The under side of the block is also provided with a groove c2, running at right angles to the groove c' and alsov 'of sufficient depth to communicate with the groove c.

It will be observed from the foregoing description that liquid coming against the under side of the guard O will first pass through 8o the groove c2, then into the groove c, and finally out through the groove c. By this means a free passage for the liquid from the bottle is provided, and at the same timethe insertion of any instrument from above is pre- Referringto the accompanying drawings, i

vented and the valve thus fully protected.

The block C is secured in position in the section b directly under'the aperture b2 by a pin c3, which passes throughv the walls of the The stopper b is'further provided with an exterior annular groove h6 for the accommodation of the elastic packing-ring 57, the purpose of which is to provide for an air-tight vjoint between the stopper b and the neck of the bottle, and thus prevent the entrance of air into the bottle. The section b is attached to the section b by being passed over the upper end of the same and secured thereto by screws or rivets.

The lower section Z1' of the stopper is provided with a conical seat Z1S,an annular internal shoulder 119, and internal vertical grooves Z111. The conical valve Z111 is adapted to lit the seat Z1s and is provided with an opening valvestem Z112, the lower end of which terminates in a head Z113, and the said valve-stein is also provided at a point between the valve portion proper and the head Z113 with a cross member Z111, the opposite ends of which are adapted to engage and slide within the grooves Z110, and thus guide the valve-stem in its movements. A coil-spring Z115 is disposed about the valvestem and bears with its opposite ends against the under side of the valve-seat and the top of the cross-bar piece Z111, said spring serving to .normally hold the valve Z111 seated to a closed position. The valve-stem Z112 passes through an apertured plate Z116, having an apertured pendent flange Z111 of less diameter than the internal diameter of the section Z1'. The plate Z116 is held to rest against the shoulder Z111 of the stopper and be suitably secured within the latter.

Z118 indicates a spherical weight or ball which is located below the liange Z111 and held in position in the section Z1 by a cross-pin Z119, passed transversely through the said section Z1'.

It will be observed by reference to Fig. 2 that the lower or head portion of the valvestem and the weight Z118 normally are so disposed relatively that the weight is disengaged therefrom, it being also seen from the drawings that the diameter of the flange Z111 and that of the ball is such that when the bottle is turned over to the position approximately that shown in Fig. 3 lthe weight will drop against the head of the valve and by reason thereof force the valve to an open position and allow for a free egress of the fluid from the bottle, which passes out through the stopper in the direction indicated by the arrow.

The pendent flange Z111, besides serving as a means for guiding the weight against the head of the valve-stem when the bottle is tilted to a properinverted position, also serves to act as a detent to hold the said weight from engaging with the said valve when the bottle is tilted at or slightly below a horizontal position, as shown in Fig. 4.

By arranging the parts in this manner it is obvious that it will be impossible to hold the bottle-neck in any such position that the iiuid may enter therein by pouring through the neck of the bot-tle, for the reason that as the spring Z115 is not opposed by the weight b18 the valve will be securely held to a closed position.

From the foregoing description, taken in connection with the accompanying drawings, it will be observed that after the bottle has once been lled and the stopper forced into the neck the latter cannot be again withdrawn, for the reason that the springs at the side thereof will serve to hold it automatically locked within the bottle-neck. Furthermore, after the bottle has once been emptied ot its contents it is impossible to again reill the saine with an inferior article, as the valve will immediately become seated upon the bottle being placed in any refillingpositiomthereby elfectually preventing the entrance of any liquid into the interior of the said bottle through the stopper. It will be further observed that when the bottle is inverted the spherical weight Z118 becomes seated upon the fiange Z111, and thus does not prevent the egress of the liquid from the bottle,which flows freely around the pendent flange Z111 and through the aperture in the side thereof and through the plate Z116.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

l. In an antirefilling bottle, the combination with the bottle proper; a valve mounted in the neck of the same; and a protectingblock mounted above the said valve and having an annular peripheral groove formed in its sides; a diametrical groove formed in its top and communicating with the annular groove at each end; a diametrical groove formed in its bottom and at right angles to the top and also communicating with the annular groove at each end, substantially as described.

2. In an antireiilling bottle; the combina tion with the bottle proper; of a hollow stopper adapted to be lapplied in the neck of the same and having internal vertical guidegrooves; a valve mounted in said stopper; a valve-stem connected to the valve; a lateralextending guide-bar mounted on said valvestem so that its opposite ends extend into the guide-grooves of the stopper, whereby it is guided in its movement and a weight mounted below said valve-stem so as to engage the latter when the bottle is inverted to open the valve, substantially as described.

In an antireiilling bottle, the combination with the bottle proper; of a hollow stop per adapted to be applied in the neck of the same, and having internal Vertical guidinggrooves; a valve mounted in said stopper; a valve-stem connected to the said valve a lat eral guide-bar mounted on the said valvestem so its opposite ends will enter the vertical guide-grooves of the stopper; a coil-spring mounted on said valve-stem and engaging said guide-bar to normally force the valvevstem downward, and a weight mounted be- IOO IIO
